Lin Yanxue's father, Lin Jingyuan, was the guard of Yanmen Pass. He was framed by the treacherous minister Gao Song and was wronged in the name of "collaboration with the enemy and treason." Lin Yanxue has since embarked on the road to clear his father's wrongdoing. Along the way, she received Xiao Ce's help. The two worked together to collect ironclad evidence of Gao Song's liaison with the Turks and the embezzlement of military rations. They went through hardships and dangers to capture Gao Song and went to the capital together to face the saint.
With the help of the loyal minister Wang and others, many evidences were presented to the emperor one by one in the early court. Gao Song's sophistry was completely exposed, his crime was exposed, and he was eventually sentenced to be executed by the Queen of Autumn, and all his accomplices were investigated and dealt with. Lin Jingyuan's grievances were cleared, he was granted the title of Marquis of Zhenguo, and his soul was enshrined in the Martyrs' Shrine to be worshiped by all people.
Afterwards, Lin Yanxue and Xiao Ce returned to Yanmen Pass to inherit Lin Jingyuan's legacy and guard the border together. Nowadays, the people of Yanmenguan live and work in peace and contentment, and the border is peaceful. The two of them are also guarding each other in the process of protecting their home and country. This journey that began with injustice finally ended with a happy ending of loyalty and justice, peace of home and country, and lovers staying together.
